Dialogic® Media Gateways (DMG Gateways) allow an IP telephony server, such as Asterisk, to operate in native IP mode while providing PSTN and/or TDM PBX connectivity. Because the connectivity is totally transparent, no load is added to the IP telephony server's operation.
Since the DMG Gateways manage all the complexities of the PSTN connection, systems can be confidently installed anywhere in the world, whether they are interfacing with analog, T1, or E1 networks. No IP telephony server software changes are necessary. The external appliance gateway handles the PSTN connection, while the server continues to operate in its native IP mode.
